Application areas of valve actuators:
Electric actuators are mainly used in the following three areas:
1. Power plant
Typical applications are:
① Application in thermal power industry
Air blower damper damper, Primary air intake damper, Air preheat damper damper, Flue gas recirculation, Bypass

electric actuator for butterfly valve

damper damper, Secondary air intake damper, Main bellows damper damper, Burner adjustment lever, Burner swing drive, Hydraulic push rod drive, Impeller Machine speed control, flue gas control valve steam, control valve, ball valve and butterfly valve, control sliding gate
②Valve actuator applications in other power industries
Ball valve dust control water jet impeller speed control control large hydraulic valve gas control valve burner ignition start steam control valve condensate recirculation, deaerator, boiler feed water, superheat controller, reheat thermostat controller, and other related valve applications
2. Process control
Used in the production process control of chemical, petrochemical, mold, food, medicine, packaging and other industries, according to established logic instructions or computer programs to accurately position, start and stop valves, tools, pipes, baffles, chutes, platforms, etc. , Opening and closing, rotation, use the temperature, pressure, flow, size, radiation, brightness, chromaticity, roughness, density and other real-time parameters detected by the system to adjust the system to realize the control of intermittent, continuous and cyclic processing .
3. Industrial automation
It is used in a wide range of aviation, aerospace, military, machinery, metallurgy, mining, transportation, building materials, etc., to adjust and control the movement points (moving parts) of various automation equipment and systems.
Examples of main applications in process control and industrial automation are as follows:
① Application in the production of sulphur ore
Water injection flow control ball valve and butterfly valve control
②Application of Potassium Carbonate Pipeline Valve Actuator
Sliding gate diverter Gate ball valve and butterfly valve Ball control valve
③Application of water treatment valve actuator
Liquid flow control, pressure regulator pressure control, acid solution flow control
④Application of valve actuator in limestone/cement plant
Ball or butterfly valve controls the treatment of dry cement, gypsum, or liquid. Air supply and induced draft fan adjustable damper damper bypass damper damper Environmental pollution control and dust removal device sliding door to control the logistics of raw materials in hoppers and storage gates control raw materials in The gas control valve at the feed port adjusts the intake air volume of the burner on the converter. The steam control valve controls the steam required for the production process.
⑤Application of actuators in grain processing plants
Gate Diverter valve Distributor Material unloader/heater Dust removal isolation baffle Air flow control (logistics drying) Ball valve and butterfly valve control
⑥Application of damper and valve actuator in steel mill
Ball or butterfly valve controls, the control of cooling water, wastewater, or other cooling media. Adjustable damper baffle air supply and induced draft fan bypass damper damper, gate Environmental pollution control and dust removal device, Sliding door controls, the flow of raw materials at the inlet to the hopper ,The raw materials in the storage warehouse are subject to logistics control, gas control valve, steam control valve, adjustment of the burner on the converter, and control of the steam required for the production process
⑦The application of damper and valve actuator in aluminum factory
Air blower damper damper, Primary air intake damper, Air preheat damper damper, Flue gas recirculation, Bypass damper damper, Secondary air intake damper, Main bellows damper damper, Burner adjustment lever, Burner swing drive, Hydraulic push rod drive, Impeller Machine speed control flue gas control, valve steam, control valve ball valve, and butterfly valve control, sliding gate
⑧Application of process control baffle
Air replenishment Exhaust fan bypass Hot/cold air mixing Emergency shutdown
⑨Application in petroleum industry
Oil injection process flow control Gas lift pipeline main valve pressure control Water injection process flow control Oil well oil quality sampling test / production valve
⑩Application in natural gas production and transportation industry
